<title>Net-SNMP: fixproc insecure temporary file creation</title>
Net-SNMP creates temporary files in an insecure manner, possibly allowing
the execution of arbitrary code.

Net-SNMP is a suite of applications used to implement the Simple
Network Management Protocol.
The fixproc application of Net-SNMP creates temporary files with
predictable filenames.
<impact type="normal">
A malicious local attacker could exploit a race condition to change the
content of the temporary files before they are executed by fixproc,
possibly leading to the execution of arbitrary code. A local attacker
could also create symbolic links in the temporary files directory,
pointing to a valid file somewhere on the filesystem. When fixproc is
executed, this would result in the file being overwritten.
There is no known workaround at this time.
All Net-SNMP users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/net-snmp-5.2.1-r1&quot;</code>
